ECOG PS
Also written as: ECOG PS — Eastern Cooperative Oncology Group Performance Status
Eastern Cooperative Oncology Group Performance Status scale measuring patient functional status and treatment tolerance.
Full Definition
The Eastern Cooperative Oncology Group Performance Status (ECOG PS) is a standardized scale used to assess a cancer patient's functional status and ability to tolerate treatment. The scale ranges from 0 to 5, where 0 indicates fully active and normal functioning, and 5 indicates death. ECOG PS is a critical factor in treatment decision-making, clinical trial eligibility, and prognosis assessment in urologic oncology. Patients with ECOG PS 0-1 are generally considered good candidates for aggressive treatments, while those with PS 3-4 may require palliative care approaches. This scoring system helps standardize patient selection criteria across clinical trials and treatment protocols, ensuring consistent communication among healthcare teams.
Usage
Usage note: Use 'ECOG PS' rather than 'ECOG performance status' to avoid redundancy.
In Context
- "The patient's ECOG PS of 2 precluded enrollment in the aggressive treatment protocol." — Clinical trial screening
- "Baseline ECOG PS was 0, indicating excellent functional status for surgical intervention." — Preoperative assessment
